SPACER FOR REENFORCING BARS.

Application filed November 29, 1918.

To all whom it may concern:

Be it known that I, VTILLIAM B. iiOUGH, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Spacers for ReenforcingBars, of which the following is a specification.

This invention relates to means for spacing the steel bars employed toreenforce concrete floors and other" structures. Such bars must besupported at the proper distance from the form-work and must be securelyheld at the desired distance from one another.

The object of the present invention is to provide a spacer of the typestated which is capable of ei'liciently performing each of its variousfunctions and which may be manufactured expeditiously and without wasteof material.

In the accompanying drawings Figure 1 is a fragmental side elevation ofone form of spacer embodying the features of my invention. Fig. 2 is atop plan view. W

519;. 3 is an under side view. Fig. is a detail view of one element ofthe construction illustrated herein.

A indicates the formwork upon which a concrete floor or the like is tobe constructed and B is one of the reenforcing bars. The bars may, ofcourse, be of any desired crosssectional form. They are spaced apartfrom one another at distances determined by the load and span, aresupported so that they shall be embedded in the desired plane in thefloor, and are secured against displacement, by means comprising asuitable number of spacers each of which comprises a longitudinal memberfolded to provide a leg or gage beneath each bar. While the longitudinalmember may be of any suitable character, l have herein shown alongitudinal member 1 consisting of a strip of band iron. The means forsupporting the reenforcing bar at the desired distance from the formworkconsists of a leg or 2 formed by folding the longitudinal member, theleg or gage being located directly below the bar.

In order to prevent the gage from uufolding or spreading and to fastenthe reenforcing bar in place, I provide a member 3 made of an integralpiece of wire folded to form tWo loops 4:, an intermediate portion 5 andtwo arms 6, the loops t and arms 6 Serial No. 264,510

extending in opposite directions from the. intermediate portion 5. Atopposite sides of the leg or gage :2 are formed openings to receive theloops 4-. in the present instance these openings are shown as formed at7 approximately midway between the opposite edges of the member 1. flierthe loops 4; have been inserted into the openings '7 said loops are bentin opposite directions so as to provide shoulders to prevent separationof the member 3 from the member 1. l-Vhen the member 3 is in place, theintermediate portion 5 spans the space between the two sites of thefolded leg or 2 and thus ties said sides together and prevents the legor gage from spreading or unfolding.

The spacer i completely asse bled at the factory, the arms (3 being bentor twisted into engagement with. the reenforcing bar after the bar hasbeen laid in place upon the formwork.

It will be apparent that the member 3 may be readily formed from wire bymeans of automatic machinery and without any "waste whatsoever.

I claim as my invention:

1. A spacer for reenforcing bars consisting of a longitudinal memberfolded to form a to underlie a reenforcing bar and space said bar fromthe formwork, said member having openings at opposite sides of the fold,and an element formed from an integral piece of Wire and comprising anintermediate portion, and. two loops, the latter extending through saidopenings and bent at the lower side of the longitudinal memher to securethe wire element in place, said. element further comprising twoupwardlyextending arms adapted to embrace and lock the reenforcing barin place.

2. A spacer tor reenforcing bars compris ing longitudinal member havinga fold therein forming adapted to underlie a reenforc' bar and spacesaid bar from the formworlr, said member having openings therein onopposite sides of the age; and an integ tie member having anintermediate portion extendingthrough said openings and spanning ,hegage, and end portions adapted to surround and embrace a reenforcingbar, said tie member having shoulders engaging the opposite sides of thegage and also the under side of the longitudinal member whereby to holdthe tie member in position upon the longitudinal member for thereception of the reenforcing bar and to restrain the gage from spreadingwhen sub jected to Weight.

3. A spacer for reenforcing bars comprising a longitudinal member havinga fold therein forming a page adapted to underlie a reenforcinp; bar andspace said bar from the formwork, said member having openings therein atopposite sides of the gage and a tie element formed Wholly of Wire andhaving means adapted to engage the opposite sides of the gage and theunder sideo'f the longitudinal member With upstanding end portionsadapted to surround and embrace a reenforcing bar placed over the gage,said means being adapted to restrain the page from spreading and to holdthe tie n ember in upright position for the reception of the reenforeingbar.

4. A tie element for securin a reenforcing; bar to a spacer bar hzwingra gage member formed therein With openings at opposite sides thereof;said element comprising an intermediate portion, a pair of loops, and apair of end portions adapted to surround and embrace a reenforcing rodplaced over said gage, said loops being adapted to be entered throughthe openings in the bar and bent laterally in opposite directions so asto engage with the under side of thebar at opposite des oi? the with theintermediate portion spanning the gage. p

A spacer for reentorcing bars comprising a longitudinal member having; adownwardly extending portion adapted to underlie a reenforcing bar. andspace said bar -from the ,formwork, said member having a slot formedtherein Which extends into said downwardly extending portion to form atransverse notch therein, and an integral tie element formed of Wireadapted to secure a reenforcing bar to said longitudinal membeijsaid tieelement comprising an intermediate portion adapted to rest in saidnotch, a pair of loops adapted to be bent laterally and engage the underside of said longitudinal member on opposite sides of said downwardlyextending; portion and a pair of end portions adapted to surround andembrace said reenforcin e; rod whereby said reeni' orc ing rod isfastened in position above said downwardly extending portion.

In testimony whereof, I have hereunto set my hand.

WILLIAM B. HOUGH.
